- To all whom it may concern;

Be it known that I, JOHN H. Koon, of Bucyrus. in the countyiofOrawfordand State of Ohio, have invented "certain new and useful. Improvementsin Tire-Upsetting Machines; and Ido hereby declare that the following isa full, clear, and exactdescription thereof, which will enable othersskilled in the "art to which it apperta'ins to make and use the same,reference being bad to the accom pan ylng drawings, and tothe lettersofreference marked thereon, which form a part of this specification, andin which- I I Figure 1 isa perspective view of myimproved tire-upsettingmachineyl lig. 2, an inverted view thereof, and Fig. 3.;a transversesection of the same. ,(lorresponding parts in are denoted by likeletters.

This invention. relates to that classof tireupsetting inachines having abisected bed, upon which thetire is clamped or held while beingupset;and it consists, inthe main, of mechanism for giving one of the sectionsof said bed a limited movement, "and of the combination therewith ofholding cam'levers, & c., substantially as hereinafter inore fully setforth.

In the annexed drawing, A A refer to a bisected bed, one of whosesections, A, is firmly bolted in position, andhas an extension, 0., uponwhich slides the other section, A. This bed is dished or concaved uponits the severalfigures upper surface to adapt it to the convexity of thetire placed thereon to be upset. 'lo-the lower side of the extension atof thesection A is fnlcrumed a lever, B, having one endconheated to thesliding section A, as shown, or

otherwise, and the other entering a camgrooved lever, G, by moving whichin one direction the bed is distended, or the section A isolated fromthe section A. The bed, thus distended, is in readiness to. receive thetire, which, when of the bed-sections A A,'and thus cause the saidlevers to occupy positions directly over the bed. Stops d,projectingfromthe levers D D, limit their backward movement.

Having thus described my invention, what I claim, and desire to secureby Letters'Patent, 1S.

1. The sliding bed-section A, in combination with the lever B, andcam-grooved lever (J, substantially as and for the purpose set forth.

2. The bed A A, having the sliding section A, in combination with thelevers B O, and holding cam-levers D D, substantially as and for thepurpose set forth. I

In testimony that I claim the foregoing as my own I hereunto affix mysignature in the presence of two witnesses.
